IMPROVED TOBACCO PAPER.

Be it known that we, P. M. Gossnnorm and RAMON ANTIGiiEIl-AD, of the city and county of New York, in the State of New York, have invented certain new and useful Improvements in the 'hLlanufaeture of Tobacco Paper; and we do hereby declare that the following is a full and exact description-thereof.

The paper is intended mainly for use as enyelopes for cigarettes, but it may be used for the bodies of cigarettes, and for the wrappers or fillings of cigars,

clothing .to preserve from moths, and in any other situation.

A demand for paper made of pure tobacco has long been felt, andefi'orts have been made to produce such.

We have succeeded in producing paper of pure tobacc0,.and can retain the whole or any desired portion of the strength of the tobacco in the product, overcoming all. thedifliculties due to the peculiar adhesive 'We will proceed to describe what we believe to be the best mode of carrying' out our invention, and will aflerward designate the points whichwe believe to be new.

In a late experimental production of one thousand water. \Ve then toolg out thetobacco, with a portion, we judge about half, of the water, and, adding some fresh water, sufiicicnt to make a proper flowing pulp, treated it from midnight until two oelock the next afternoon, in other words, fourteen hours, continuously, in the ordinary beating or pulping-engine ofthe papermill. We treated the stems and leaves mingled, believing that the coarse fibre of the stems is useful in imparting valuable qualities to the product. We then flowed out the pulpthus made in the ordinary Foudrinier machine, blit so adjusted as to produce a tolerably thick paper, about like the medium brown paper used for wrappiiig-purposes.

In passing the pulp through theFoudrinier machine, we la d sheets of previously-made common paper, or, better, similar paper, between the pulp and the-several rollers, and thus avoided the diliiculty which would otherwise result from the adhesion of the peculiar material to the rollers.

These sheets of paper do not permanently adhere to-the soft pulp, but are easily separated therefrom after the sheet of pulp has passed the rollers.

We found this proceeding more especially needed at the commencement of the operation.

We found, alter the machine was fairly working, that the tenacity otthc material was sutiicir-nt, ordinarily, to peel off the partially-formed paper from the rollers, but whenever any diliiculty arose from sticking, the attendin a dry condition at band for the purpose. Thus, whenever inclined to stick to the rollers, the partially-formed paper was treated between the several rollers, not by contact with the rollers directly, but by contact with the sheets of paper which were interposed between thi pulp and the rollers.

Paper may be thus used in continuous sheets of great length, and the interposition be made practically continuous, but we have not found it necessary, and believe it bestto simply introduce it in sheets, as circumstances show it to be required, omitting it for such part of the time as the pulp can be induced to work without stickmg.

We believe that our method will, with proper care, insure a reproduction of the new and valuableprodnct obtained, with proper precautions, at any time.

Byavoiding the introduction of alkalies, or any chemicals, We can omit the washing heretofore considered necessary; and preserving the original strength of the tobacco in the leaf itself and in the Water in which it is softened, we can, by using the whole or any-desired quantity of the Water fiom the tank or kettle in the pulping-engine, retain the whole or any desired portion of the strength of the tobacco in the final paper.

' We can, by employing a longer time in the prepare tory stage, soften the tobacco incold or tepid water,

instead of boiling it,'and,we have tried the employment of steam as an agent with success, believing that we soften the material a little soonerwith steam than with boiling water.

It is essential simply to this stage of our process that we soften it by the use of water or watery vapor, without chemicals, and thus'avoid any necessity tbrchaing" ing waters and losing-the strength of the tobacco.

Our paper may be calender-ed, and thereby smoothed or glazed like other paper. It may be sized and may receive any ordinary additions; but what we esteem especially valuable in the product, is the preservation of such part as is desired of the strength of the tobacco,

and preserving its puritypby avoiding the addition'oi' i any obnoxious foreign substances, and preserving all the several; elements in their original intimate relations, without distillation or other change.

We do not claim separating the extractive matterand again reiniiising it alter the paper is finished, as it; is well known that different properties are imparted by such treatment, and the article thereby produced is interior; but, having now fully described our invention,

What we claim as new, and desire to secure by Letters Patent, is as follows:

\Ve claim the within-described tobacco paper, made from tobacco, substantially in the manner described, and retaining the whole era large part of the original strength and properties of the plant, as and for the pur poses herein described.
